After a decade of near-zero growth in methane levels, "globally averaged atmospheric methane increased by [approximately] 7 nmol/mol per year during 2007 and 2008. During the first half of 2009, globally averaged atmospheric CH 4 was [approximately] 7 nmol/mol greater than it was in 2008, suggesting that the increase will continue in 2009."
Globally averaged atmospheric concentration and its annual growth rate. [17] In April 2022, NOAA reported an annual increase in global atmospheric methane of 17 parts per billion (ppb) in 2021—averaging 1,895.7 ppb in that year—the largest annual increase recorded since systematic measurements began in 1983; the increase during 2020 was 15.3 ppb, itself a record increase.
The following table lists the 1970, 1990, 2000, 2010, 2020, 2021, 2022 and 2023 annual per capita GHG [n 1] emissions estimates (in metric tons of CO 2 equivalent per year). The data include carbon dioxide (CO 2), methane (CH 4) and nitrous oxide (N 2 O) from all sources, including agriculture and land use change. They are measured in carbon ...
Methane traps about 28 times the heat per molecule as carbon dioxide but lasts a decade or so in the atmosphere instead of centuries or thousands of years like carbon dioxide, according to the U.S ...
The world saw a record jump in levels of methane in the atmosphere last year as the main heat-trapping greenhouse gases reached new highs, UN experts said. ... The report is one of a number of ...
Emissions attributed to specific power stations around the world, color-coded by type of fuel used at the station. Lower half focuses on Europe and Asia [1]. This article is a list of locations and entities by greenhouse gas emissions, i.e. the greenhouse gas emissions from companies, activities, and countries on Earth which cause climate change.
Methane traps about 28 times the heat per molecule as carbon dioxide but lasts a decade or so in the atmosphere instead of centuries or thousands of years like carbon dioxide, according to the U.S. Environmental Protection Agency. Carbon dioxide and methane levels have been higher in the far ancient past, but it was before humans existed.
